Tuning Ni-Foam into NiOOH/FeOOH Heterostructures toward Superior Water Oxidation Catalyst via Three-Step Strategy.

Splitting of water into hydrogen and oxygen has become a strategic research topic. In the two semi-reactions of water splitting, water oxidation is preferred to the four-electron-transfer process with a higher overpotential (η) and is the decisive step in water splitting. Therefore, efficient water oxidation catalysts must be developed.

Long-term outcomes of superficial neoplasia at the esophagogastric junction treated via endoscopic submucosal dissection and endoscopic submucosal tunnel dissection: a cohort study of a single center from China.

Background And Aims: The techniques and indications for endoscopic submucosal dissection (ESD) and endoscopic submucosal tunnel dissection (ESTD) to remove superficial neoplasia at the esophagogastric junction (EGJ) have been developed and expanded. However, the resection of superficial neoplasia at the EGJ by ESD remains challenging, and the long-term clinical outcomes of curative and non-curative resections based on histological criteria remain unclear. We conducted a retrospective analysis on the safety and efficacy of the ESD and ESTD procedure with these patients.

Enhancing the thermal stability of the carbon-based perovskite solar cells by using a Cs FA PbBr I light absorber.

Despite the impressive photovoltaic performance with a power conversion efficiency beyond 23%, perovskite solar cells (PSCs) suffer from poor long-term stability, failing by far the market requirements. Although many efforts have been made towards improving the stability of PSCs, the thermal stability of PSCs with CHNHPbI as a perovskite and organic hole-transport material (HTM) remains a challenge. In this study, we employed the thermally stable (NH)CHPbI (FAPbI) as the light absorber for the carbon-based and HTM-free PSCs, which can be fabricated by screen printing.

Clinical experience of using a novel self-help inflatable balloon to prevent esophageal stricture after circumferential endoscopic submucosal dissection.

Although endoscopic submucosal dissection (ESD) is gradually becoming a first-line treatment for superficial esophageal neoplasms (SEN), strictures occur in almost 100% of cases after circumferential ESD. A standard method to prevent stricture has not been established. Thus, we propose a novel self-help inflatable balloon to prevent stricture.

Consensus on the digestive endoscopic tunnel technique.

With the digestive endoscopic tunnel technique (DETT), many diseases that previously would have been treated by surgery are now endoscopically curable by establishing a submucosal tunnel between the mucosa and muscularis propria (MP). Through the tunnel, endoscopic diagnosis or treatment is performed for lesions in the mucosa, in the MP, and even outside the gastrointestinal (GI) tract. At present, the tunnel technique application range covers the following: (1) Treatment of lesions originating from the mucosal layer, .

Podocyte histone deacetylase activity regulates murine and human glomerular diseases.

We identified 2 genes, histone deacetylase 1 (HDAC1) and HDAC2, contributing to the pathogenesis of proteinuric kidney diseases, the leading cause of end-stage kidney disease. mRNA expression profiling from proteinuric mouse glomeruli was linked to Connectivity Map databases, identifying HDAC1 and HDAC2 with the differentially expressed gene set reversible by HDAC inhibitors. In numerous progressive glomerular disease models, treatment with valproic acid (a class I HDAC inhibitor) or SAHA (a pan-HDAC inhibitor) mitigated the degree of proteinuria and glomerulosclerosis, leading to a striking increase in survival.

Clinical outcomes of endoscopic resection for non-ampullary duodenal laterally spreading tumors.

Edge/Defect-Rich, Metallic, and Oxygen-Heteroatom-Doped WS Superstructure with Superior Electrocatalytic Performance for Green Solar Energy Conversion.

Two-dimensional tungsten sulfide is widely applied in electrocatalysis. However, WS possesses catalytic active sites located at the layer edge and an inert surface for catalysis. Therefore, increasing the exposure of active sites at the edge and effectively activating the inert sites on the surface is an important challenge.

Efficacy of triamcinolone-soaked polyglycolic acid sheet plus fully covered metal stent for preventing stricture formation after large esophageal endoscopic submucosal dissection.

Esophageal stricture is a major problem for patients with large superficial esophageal squamous cell neoplasms (SESCNs) after endoscopic submucosal dissection (ESD). Although many measures could be used as prophylaxis for post-ESD strictures, a well-accepted method has not yet been established. We propose using a triamcinolone-soaked polyglycolic acid sheet plus fully covered metal stent (TS-PGA+FCMS) as a novel method to prevent stricture formation after large esophageal ESD.

Alleviate the - hysteresis of carbon-based perovskite solar cells introducing additional methylammonium chloride into MAPbI precursor.

The hysteretic phenomenon commonly exists in the - curves of perovskite solar cells with different structures, especially for carbon-based mesoscopic perovskite solar cells without hole-conductor (carbon-based PSCs). By adding moderate amounts of methylammonium chloride (MACl) into MAPbI perovskite precursor, we found the - hysteresis of carbon-based PSCs could be significantly alleviated and the crystallinity of MAPbI perovskite could also be influenced. With the increasing amount of MACl, MAPbI perovskite showed better and better crystallinity until the MACl came to 0.
